Vanishing Glaciers in Peru

according to a 2012 paper by the University of Texas and the Huascaran National Park.

Peru is home to 71% of the world’s tropical glaciers, which are a source of fresh water for millions, but 22% of the surface area of Peruvian glaciers has disappeared in the past 30 years alone, according to The World Bank. Environmental issues were under the spotlight during a working group of the Intergovernmental Panel on Climate Change (IPCC), who met in Stockholm from September 23-27, 2013.

Leading climate scientists said they were more convinced than ever that humans are the main culprits for global warming, and predicted the impact from greenhouse gas emissions could linger for centuries. The IPCC said in a report that a hiatus in warming this century, when temperatures have risen more slowly despite growing emissions, was a natural variation that would not last. It said the Earth was set for more heatwaves, floods, droughts and rising sea levels from melting ice sheets that could swamp coasts and low-lying islands as greenhouse gases built up in the atmosphere.
